Corporate distribution networks for slot array antenna based on groove gap waveguide technology

摘要

This paper deals with the design of low loss wideband power dividers based on groove gap waveguide (GGW) technology. The advantages of GGW power dividers are low insertion loss, high power handling capacities, ease of fabrication and compatibility with integrated microwave networks. A 64-way power divider is designed and used as the feeding network of a 16×16-element slot antenna array at 60-GHz band. The results show that the gain and total radiation efficiency of the antenna are more than 32.5 dBi and 90% over the desired frequency range from 56 to 66.4 GHz.
